I have been an avid deer hunter in MN for 15+ years now and have typically been hunting the Shotgun and Bow seasons here. I am now interested in the new challenge of hunting with a MuzzleLoader. I am looking on advice for a good starter gun or set and if anyone knows of any classes or anything I can take to teach me how to operate my new weapon once it is purchased.

Thanks for any help you can give.

Have a look this will help not a class but gives you a full rundown from start to finish with detailed explanation MidwestProwler's channel - YouTube
